Abstract: 1399146 Making two-part travellers LITTON INDUSTRIES Inc 24 Nov 1972 54539/72 Heading B3A [Also in Division D1] A method of manufacturing a plurality of travellers 22, Fig. 5, each traveller having at least one synthetic plastics portion 20 and a metal wire portion 14 comprises moulding a plurality of synthetic plastics runner portions, at least some of which are runner portions for the travellers, on a continuous metal wire 14 in spaced-apart relationship, and severing the wire intermediate the runner portions whereby discrete travellers each comprising a runner portion with a wire extending therefrom are formed. Synthetic plastics is deposited in a plurality of recesses 16, 18, Fig. 1, formed in dies 10, 11 placed between platens (not shown). The wire, which is heat treated to increase its hardness, is either fed from a reel (not shown) or provided in long staight lengths and passes through each recess to provide a plurality of runner portions simultaneously on the wire. It can then be taken up on a reel (not shown) on a pivotally mounted arm biased to maintain a constant tension on the wire. The wire and runners are then fed into a wire forming machine which severs the wire adjacent one side of each portion 20 to form travellers, Fig. 3 (not shown), which are then bent, Fig. 4 (not shown). The resilience of the plastics and the wire is sufficient to allow the traveller to be strapped into place on a spinning ring 30 and easily removed therefrom. A further embodiment, Fig. 8 (not shown), includes a separate plastics head (42) distinct from a body portion (40). The travellers may be shaped differently, Fig. 7 (not shown), and the wire may be severed and bent along the outer surface of the runner portion to increase its rigidity. The surface of the wire portion may be treated to increase its wear resistance, e.g. by flame spraying.

Abstract: 1,184,409. Television. INTERNATIONAL VIDEO CORP. 9 Dec., 1968 [11 Dec., 1967], No. 58372/68. Heading H4F. To record and reproduce two signals having separate high and low frequency ranges, such as the video and audio frequency signals (inputs 41 and 59) derived from a combined television signal, on the same area of a magnetic tape 10 such that there is no interference between the two signals, the video signal (frequency modulated on a carrier) is recorded at a higher writing speed than the audio signal, the audio signal to be recorded being limited by a low-pass filter 61 to frequencies which when multiplied by the ratio of the writing speeds are below the lowest desired frequency of the reproduced video signal, and the reproduced video signal is limited by a high-pass filter 46 to frequencies above this lowest frequency. As shown the audio signal recording head 51 is moved in a direction parallel to the longitudinal direction of magnetic tape 10 and the video signal recording head 24 comprises a helical scan recording head although it may comprise a transverse scan recording head. The tape drive motor 18A and the video head motor 22A are controlled by speed control unit 28 which receives a reference signal from source 30, and during recording a control signal is recorded on the magnetic tape by head 50, which control signal is applied to unit 28 during playback. Low-pass filter 55 for the control signal is the same as low-pass filter 61 for the audio signal. The arrangement is such that the ratio of the lower frequency of the high-pass filter 46 to the upper frequency of the (or each) low-pass filter is at least N, e.g. 100, where N is the ratio of the video writing speed to the audio (and control signal) writing speed. Thus an audio signal picked up by the video head and multiplied in frequency by the ratio of the writing speeds is below the reproduced video signal frequencies or may be removed by filter 46 from the video signal without the removal of any frequencies within the video band. In addition to the low frequency audio and control signals, further low frequency signals, e.g. auxiliary signal 64, may be recorded at the low writing speed.
